Question 1:
Which of the following is the primary function of the immune system?
A. To produce insulin
B. To transport oxygen
C. To defend against pathogens
D. To regulate blood pressure
Correct Option: C. To defend against pathogens
Rationale: The primary function of the immune system is to recognize and eliminate pathogens
such as bacteria, viruses, and other foreign substances that enter the body.
Question 2:
A patient undergoing chemotherapy is at increased risk for infection due to which of the
following?
A. Increased appetite
B. Myelosuppression
C. Improved circulation
D. Enhanced immune response
Correct Option: B. Myelosuppression
Rationale: Myelosuppression is a common side effect of chemotherapy that decreases bone
marrow activity, leading to reduced production of white blood cells, which increases the risk of
infection.
Question 3:
Which laboratory value indicates the presence of an active infection in a patient?
A. Low hemoglobin
B. Elevated white blood cell count (WBC)

C. Normal platelet count
D. Decreased serum albumin
Correct Option: B. Elevated white blood cell count (WBC)
Rationale: An elevated white blood cell count typically indicates that the body is responding to
an infection or other inflammatory process.
Question 4:
In the context of oncology, which of the following is considered a hallmark of cancer?
A. Sustained proliferative signaling
B. Normal apoptosis
C. Decreased metabolic activity
D. Stable genome
Correct Option: A. Sustained proliferative signaling
Rationale: One of the hallmarks of cancer is the ability of cancer cells to continuously signal for
proliferation, allowing them to grow uncontrollably.
Question 5:
What is the primary goal of palliative care in oncology?
A. To cure the disease
B. To manage symptoms and improve quality of life
C. To increase survival time
D. To eliminate the need for further treatment
Correct Option: B. To manage symptoms and improve quality of life
Rationale: Palliative care focuses on relieving symptoms and enhancing the quality of life for
patients with serious illnesses, including cancer, rather than seeking to cure the illness.
Question 6:
Which type of immunity is developed after exposure to an infectious agent?
